I thought this was worth mentioning in light of the fact that virtually every cinematic incarnation of Body Snatchers involves some sort of love relationship gone awry. We have divorcees Becky and Miles in the 1950s version -- both the products of failed marriages. We have unhappily married Elizabeth attracted to Bennell in the 1978 take, and her husband is one of the parasites. Even the latest version, in 2007, lands a female Bennell (Nicole Kidman) in a failed marriage and seeking love with another suitor (Daniel Craig). The romantic love relationship - this passionate, connection to a human being - is always the "thing" that is in danger of being lost in the films, though (for better or worse...) The Invasion adds the element of parental love. But more than that when we get to it.
